Some CaK Sunnage

[barx1963]

Finally managed a semi decent CaK image today. Original video of 3000 frames processed down to 1500 in PIPP and Registax 6. Final tweaks (colour, crop and some levels in PS)
Taken with an ASI 290MM camera, SW80ED cope with a Lunt CaK filter. Captured with Firecapture.

Nice image!


I don't know if i better buying a dedicated solar scope or buying kind of filters or accessories that i can attach to standard scopes then i can shot the sun, i don't know what will be the difference then.

Tareq,
It's getting more and more difficult to obtain good external etalon (H alpha) filters to use (with a blocking filter) on standard telescopes.

The Daystar Quark seems to be a popular alternative.
The Lunt Cak filter is also available.

I am talking about those Quark or Lunt filter or even something like white light to be used with standard scopes rather than dedicated solar scopes such as Lunt itself or Conorado and such.

Tariq,
A Baader solar film white light might be a cost effective option for the next few years, until the activity level picks up.

Does this activity level all the global or to some parts of earth? I asked because we live in very hot region and the sun is nearly closer to us than other parts and always strong, so i thought maybe we can see solar activities more than other parts of the world.

[Ukastronomer]

Daystar, Iagree, though I would not personally spend the money on CaK

[Merlin66]

Tareq,
It's part of the 11 year solar cycle, next maximum activity should be around 2024.

There has always been something about a good CAK image; I just love them but not sure about the outlay to get images myself. Nice image

[Ukastronomer]

Same here, but to me it just looks like Ha in blue so ill stay with just ha

Remember the sun is roughly 150,000,000kms away. The difference between various parts of the world in terms of distance is at most measured in the 1000s of kms. The difference in temperature between areas closer to the equator and those further away is more to do the the angle of the sun relative to the surface rather than distance. The sun will look much the same all over the world. A small advantage those closer to the equator have is (on average) the get to observe through less atmosphere which can help. The biggest factor in clarity of images is how much the atmosphere is moving (the seeing)

Cheers
